Which of the following examples shows the general structure of a for loop in a shell script?

Answer options

• A. for *.txt as file => echo $file
• B. for *.txt ( echo $i )
• C. for file in *.txt do echo $i done
• D. for ls *.txt exec {} \;
• E. foreach @{file} { echo $i }

Correct answer: C

Explanation

Option C is correct because it accurately represents the syntax of a for loop in a shell script, using 'for file in *.txt' followed by the commands to execute. The other options either use incorrect syntax or are not valid constructs in a shell script context.
